Diagnostic and Therapy for Breast Cancer

This project aims to address the unmet need for effective targeted therapies in endocrine therapy-resistant, recurrent, estrogen receptor-positive (ER+) breast cancers and triple-negative breast cancers. The researchers plan to develop and test a novel diagnostic and companion therapy for semaphorin 7a (SEMA7A) expression, which has been identified as upregulated in a significant percentage of breast cancer patients and a potent driver of metastasis in preclinical models. They will validate the diagnostic in a large cohort and explore the feasibility and efficacy of a monoclonal antibody-based therapy targeting SEMA7A. The goal is to develop and test the antibody-based diagnostic and therapy, potentially leading to clinical trials to determine whether SEMA7A can predict treatment outcomes in breast cancer patients, particularly in a high-risk subset of young ER+ postpartum patients. The research team's expertise in various areas, including basic science, monoclonal antibody development, pre-clinical testing, and clinical trials, positions them to advance this innovative approach towards improving breast cancer treatment and patient outcomes.
